Vegan Outreach have a completely free program for people who might need a little support when going vegan. You can also sign up if you're already vegan and want to help someone else! The Vegan Mentor Program writes about their service like this:
"Get connected via email with a volunteer mentor who will help you with anything from navigating the grocery store aisles to figuring out how to respond when people ask you questions. As of May 2017, the Vegan Mentor Program (Programa Mentor Vegano en Español) has over 1,900 mentors located in 1,000 cities in 60 countries."
You can either sign up for the English version or the Spanish one.
